CoreWeave's 15-year lease turns a Niagara cryptomine into credit

CoreWeave has signed a definitive anchor lease at Blockfusion's campus in Niagara Falls, New York, a 15-year commitment with two five-year renewal options at a site that spent the previous decade mining bitcoin. The news reached the market this week through Blue Acquisition Corp., the Nasdaq-listed special purpose acquisition company merging with Blockfusion — the entity whose shareholder story depends on the campus being filled.

Blockfusion USA said its wholly owned subsidiary, North East Data, LLC, signed the lease, following the non-binding letter of intent announced in June, when Blockfusion put the deal at up to 300MW including 85MW of guaranteed take-or-pay capacity. The June version attached a revenue estimate to that guaranteed portion: roughly $2.8 billion across the initial 15-year term, or about $5.4 billion with both renewal options exercised. This week's announcement did not restate the capacity or the dollars, and the coverage does not say whether the executed lease carries the same terms. That leaves the two numbers that made the June version interesting still attached to a letter of intent.

Those June figures remain the best available price for the campus, and they repay running: 85MW of guaranteed capacity producing $2.8 billion over 15 years works out to about $2.2 million per megawatt per year. Extend through both renewals and the shape changes: the second and third five-year terms add $2.6 billion over ten years, roughly $3.1 million per megawatt-year, which implies either meaningful escalators inside the base term or renewal pricing struck above it. This year's infrastructure announcements disclose position and withhold price; Niagara Falls ran the order the other way, with the dollars arriving in June and the definitive signing adding none of its own.

Blockfusion's route to the lease is the instructive part: the company converted a decommissioned power plant into a cryptomine campus and is now adapting the property for high-density, liquid-cooled AI infrastructure, two reuses of a single grid connection. Chief executive Alex Martini-Lo Manto called the agreement a defining milestone and a validation of the campus, and framed the work as transforming a former industrial site into infrastructure for the next generation of computing. In this market, the queue, the permit and the connection now trade before the electron does, and a campus that already holds its interconnection skips the constraint that sets the pace for most new AI capacity. That is what makes a decommissioned power plant with a cryptomine on it the address for a 15-year AI lease.

CoreWeave's landlord list says the same thing. The AI cloud firm largely relies on third parties for its data center capacity, developing some sites itself, and has leased across North America from Core Scientific, Galaxy, Applied Digital, Related Digital, Chirisa Technology Parks, Lincoln, Flexential, TierPoint, Digital Realty, DataBank, Switch, Digital Crossroads, eStruxture, Bell Canada and others. Several of those names arrived at AI hosting through crypto mining, as Blockfusion did, and the capacity that once ran mining rigs is being rebuilt on the same pattern. Its customers include OpenAI, Microsoft, IBM, Nvidia and Meta, a roster that explains how a 15-year take-or-pay commitment becomes available at all.

The sequencing matters: the June letter of intent went out under Blockfusion's name, while the definitive lease went out through Blue Acquisition, the entity merging with it. A signed anchor lease with a named counterparty is the document a SPAC's shareholder base most wants to see, and CoreWeave, which leases from so many landlords across North America, is among the counterparties best positioned to supply one.

An anchor lease this long does two things, and only one of them is about data centers. It sells the campus's power rights forward at AI prices, so Blockfusion no longer has to guess what a guaranteed megawatt is worth in 2034. It also hands Blue Acquisition a contracted revenue line to put in front of shareholders ahead of the merger — the most persuasive item on the page for a platform heading to public markets.

Neither use settles the question a lender should be asking: whose credit sits behind the 85MW. A take-or-pay is only as firm as its tenant, and the tenant's ability to pay rests on contracts that rest on demand from OpenAI, Microsoft, IBM, Nvidia and Meta. That chain is real — several layers of counterparty removed from a hyperscaler signature on the same page, but a chain all the same — and it is the reason converted cryptomines can borrow against AI demand at all. The capital hierarchy in this market, in which hyperscaler-anchored assets clear at infrastructure pricing while everything else fights for capital, puts an anchor lease to an AI cloud provider near the front of the queue. Pricing it there means pricing CoreWeave's contract book as the underlying asset: a defensible trade on paper this long, and a different trade from leasing the same megawatts to Microsoft.

What happens to the rest of the campus remains a forecast. June's letter described up to 300MW with 85MW guaranteed, and this week's announcement does not disclose the executed lease's coverage, leaving as much as 215MW uncontracted on June's numbers. Robert Restaino, the mayor of Niagara Falls, said the investment creates opportunities for residents, businesses and future generations — a converted industrial site with a city behind it is the easy end of the consent problem, which now binds as tightly as capital. For Blockfusion the nearer question is the second tenant, and the terms of the next lease will say more about what Niagara Falls is worth than the anchor did.
